Added pager settable parameter to control the command used to display paged output

Also:
- ppaged() now uses the pager settable parameter
- By default the pager settable parameter uses the PAGER environment variable if present
- If PAGER environment variable is not present, pager gets set to:
    - "less -SXRF" on POSIX OSes (macOS and Linux)
    - "more" on Windows
